Anatomical and physiological responses of roots and rhizomes in Oryza longistaminata to soil water gradients. [PDF]

Ann Bot
Abstract Background and Aims Roots and rhizomes are crucial for the adaptation of clonal plants to soil water gradients. Oryza longistaminata, a rhizomatous wild rice, is of particular interest for perennial rice breeding owing to its resilience in abiotic stress conditions.

Principal component analysis of morpho-floral traits in Oryza sativa × Oryza longistaminata advanced backcross lines of rice

Journal of Experimental Biology and Agricultural Sciences
Hybrid rice technology substantially improves the food security of South Asian countries where rice (Oryza sativa L.) is a staple food. Several traits contribute to hybrid seed production efficiency, among which stigma exsertion is crucial for enhancing ...

Assembling the genome of the African wild rice Oryza longistaminata by exploiting synteny in closely related Oryza species. [PDF]

Commun Biol, 2018
AbstractThe African wild rice species Oryza longistaminata has several beneficial traits compared to cultivated rice species, such as resistance to biotic stresses, clonal propagation via rhizomes, and increased biomass production. To facilitate breeding efforts and functional genomics studies, we de-novo assembled a high-quality, haploid-phased genome.

In Silico Characterization of a Cyclin Dependent Kinase -A (CDKA) and its Coding Gene in some Oryza Species

مجلة بغداد للعلوم, 2020
Rice (Oryza sativa) is a fundamental food for the majority of world population. Cyclin Dependent Kinase -A (CDKA) accelerates transition through different stages of cell cycle and contributes in gametes formation.

Conservation of crop wild relative diversity in Northeast Africa: Checklist and prioritization

Crop Science, Volume 63, Issue 6, Page 3430-3442, November/December 2023., 2023
Abstract Crop wild relatives (CWR) are an important source of genetic diversity useful for crop improvement. This study was conducted to create both a checklist and a priority inventory of CWR in Northeast Africa. A partial CWR regional checklist was obtained by combining the floras of Djibouti, Ethiopia and Eritrea, Somalia, South Sudan, and Sudan for

Genetic diversity and differentiation of the African wild rice (Oryza longistaminata chev. et roehr) in Ethiopia

Scientific African, 2019
Undomesticated rice species (Oryza longistaminata) which possessed AA genome as O. sativa, is native to Africa and a good candidate for widening the cultivated rice gene pool. So as to use O.

PHOSPHORUS‐STARVATION TOLERANCE 1 (OsPSTOL1) is prevalent in upland rice and enhances root growth and hastens low phosphate signaling in wheat

Plant, Cell &Environment, Volume 46, Issue 7, Page 2187-2205, July 2023., 2023
Abstract PHOSPHORUS‐STARVATION TOLERANCE 1 (OsPSTOL1) is a variably present gene that benefits crown root growth and phosphorus (P) sufficiency in rice (Oryza sativa). To explore the ecophysiological importance of this gene, we performed a biogeographic survey of landraces and cultivars, confirming that functional OsPSTOL1 alleles prevail in low ...
